Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valves, in particular to a high-precision safety explosion-proof valve body. Background Art
[0002] An exhaust valve is usually used in conjunction with equipment such as pipelines or liquid containers. The exhaust valve can ensure that the air inside the container is discharged, thereby ensuring the safety of the inside of the container. However, when the existing exhaust valve is in use, when the liquid inside the container decreases, the outside air cannot replenish the inside with air in time, resulting in a large pressure difference between the inside and the outside. There are safety risks during use, and a separate air intake valve is required for cooperation. The installation and use costs are high during use, and it is easy to malfunction during use.
[0003] When liquid is added in the half-volume condition, a vacuum space is formed inside because no air enters, and liquid cannot be added smoothly. The existing exhaust valve has an asymmetric main structure during production, so the efficiency during production and installation is relatively low, and the installation cost is also relatively high.
[0004] The company previously installed a high-precision valve. During production, the combination and installation of the connecting structures were troublesome, the production efficiency was relatively low, and the safety and durability of the internal valve core during activities were relatively poor. The explosion-proof performance during use was also relatively poor. Therefore, it was necessary to carry out product innovation based on the original valve. Utility Model Content
[0005] The purpose of the utility model is to provide a high-precision safety explosion-proof valve body, which improves the structure of the original product, and the internal main valve structure position is connected with a structure that is symmetrical up and down. When in use, a limiting structure is set between the internal exhaust chamber and the exhaust valve core, so that the position accuracy of the valve core when it is active can be more guaranteed, and an interlaced air delivery space can be formed between the limiting structures, and the structural strength is higher. When the internal liquid is reduced, air can be added to the interior in time and automatically, ensuring the consistency of the air pressure inside and outside, effectively reducing the danger during use, and when the internal liquid is filled, the existence of vacuum space can be avoided, ensuring better overall smoothness during the filling process, and better activity smoothness and safety of use during use, so that the accuracy of the exhaust position during exhaust can be effectively improved, the overall durability during use is stronger, and it can meet the use requirements of application equipment with relatively high safety and precision requirements.
[0006] The technical solution of the utility model is as follows:
[0007] A high-precision safety explosion-proof valve body, including a main valve body structure, characterized in that: an exhaust valve chamber with an opening upward is provided inside the main valve body structure, and an exhaust stabilization limit column uniformly distributed on the inner side wall of the exhaust valve chamber is provided, and the exhaust stabilization limit column is composed of a first limit matching column and a second limit matching column distributed up and down, the projections of the first limit matching column and the second limit matching column in the up and down directions are circumferentially staggered, the lower end surface of the first limit matching column and the upper end surface of the second limit matching column are on the same plane, an exhaust valve core body is installed inside the exhaust valve chamber, the exhaust valve core body is a spherical structure that is symmetrical in the up and down directions, and a cylindrical stabilization matching column is provided between the upper and lower spherical structures, the diameter of the stabilization matching column is the same as the diameter of the upper and lower spherical structures, an exhaust safety matching ring is respectively provided at the upper end of the first limit matching column and the lower end of the second limit matching column, and the outer side of the exhaust safety matching ring in the up and down directions is located at The closure of the valve core is connected with the closure of the valve body by a sealing engagement ring, and the closure of the valve body is connected with the closure of the valve body by a sealing engagement ring.
[0008] Furthermore, the diameter of the main body delivery fitting hole is larger than the diameter of the exhaust transition hole set at the center position of the sealing safety fitting pad and the exhaust safety fitting ring.
[0009] Furthermore, sealing matching safety grooves are provided on both the upper and lower sides of the exhaust safety matching ring.
[0010] Beneficial effects of the utility model:
[0011] 1. The utility model adopts a brand-new structural design. When in use, a limiting structure is set between the internal exhaust chamber and the exhaust valve core, so that a second exhaust space is formed between adjacent limiting structures. When the internal liquid is reduced, air can be added to the interior in time and automatically, ensuring that the air pressure inside and outside is consistent, effectively reducing safety hazards during use.
[0012] 2. When filling the internal liquid, the existence of vacuum space can be avoided, ensuring better overall smoothness during the filling process. The internal valve core can move regularly when used in conjunction, and the movement smoothness and safety during use are better, thereby effectively improving the accuracy of the exhaust position during exhaust. The overall durability during use is stronger and can meet the use requirements of application equipment with relatively high safety and precision requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] like Figures 1 to 8As shown, a high-precision safety explosion-proof valve body includes a main valve body structure 1. The arrangement of the valve body lower pipe 6 enables the main structure to form a structure that is symmetrical from top to bottom, which is convenient for production and later assembly. The main valve body structure 1 is provided with an exhaust valve chamber 3 that opens upward, and the inner side wall of the exhaust valve chamber 3 is provided with an exhaust stabilization limit column 4 that is evenly distributed circumferentially. The exhaust stabilization limit column 4 is composed of a first limit matching column 41 and a second limit matching column 42 that are distributed up and down. The projections of the first limit matching column 41 and the second limit matching column 42 in the up and down directions are staggered in the circumference. The lower end face of the first limit matching column 41 and the upper end face of the second limit matching column 42 are on the same plane, which can ensure the strength of the main structure and provide a larger space inside. The end faces at the upper and lower positions can also play a role in limit matching during combined installation. The exhaust valve core body 5 is installed inside the exhaust valve chamber 3. The exhaust valve core body 5 is a symmetrical spherical structure in the upper and lower directions. There is a cylindrical stable matching column between the upper and lower spherical structures. When moving, the middle cylindrical surface can be matched, so that the matching contact space during the activity is larger and the stability is better. In addition, with the limiting structure, regular and accurate movement matching can be achieved, thereby ensuring the precise movement of the exhaust valve. The diameter of the stable matching column is the same as the diameter of the upper and lower spherical structure, ensuring that the strength of the valve core structure is better and the space at the lower end is larger. An exhaust safety matching ring 8 is respectively provided at the upper end of the first limiting matching column 41 and the lower end of the second limiting matching column 42. A sealing safety matching pad 9 is provided at the outer position of the exhaust safety matching ring 8 in the upper and lower directions. The upper end of the sealing safety matching pad 9 at the upper end is matched and connected with a valve body upper pipe 10. The valve body upper pipe 10, the sealing safety matching pad 9, the exhaust safety matching ring 8 and the main valve body structure 1 are fastened together by a combined locking connection seat 11. The sealing safety mating pad 9 at the lower end is connected with the valve body lower pipe 6. The valve body lower pipe 6 is also fastened with the sealing safety mating pad 9 at the lower end, the exhaust safety mating ring 8 and the main valve body structure 1 through a combined locking connection seat 11, ensuring that the combined structure at the upper and lower positions of the valve body forms a symmetrical structure, which is easier to install and more convenient to produce. At the same time, it can also ensure that the safety is more stable during use. The sealing safety mating pad 9 and the exhaust safety mating ring 8 are provided with an exhaust transition hole at the center position. The interior of the valve body upper pipe 10 is a hollow structure. The outer side of the valve body upper pipe 10 is provided with a main exhaust output hole 12 evenly distributed around the circumference near the upper end, which is the main exhaust port when used as a whole. When the exhaust valve core body 5 moves up and down, the upper end position can be completely sealed and matched with the exhaust transition hole on the exhaust safety mating ring 8. The interior of the valve body lower pipe 6 is provided with a hollow main body delivery matching hole 7 to ensure the liquid delivery matching at the lower end.A combined stable sealing seat 2 is provided between the valve body lower pipe 6 and the exhaust safety matching ring 8, which ensures better sealing stability of the internal structure. When performing maintenance during long-term use, the replacement of this component can ensure the sealing stability between the matching structures, and the efficiency of maintenance is higher. The structure inside the valve core adopts a brand-new structural design. When in use, a limiting structure is set between the internal exhaust chamber and the exhaust valve core, so that a second exhaust space is formed between adjacent limiting structures. When reducing the internal liquid, air can be added to the interior in a timely and automatic manner, ensuring that the air pressure inside and outside is consistent, effectively reducing the safety during use, and when filling the internal liquid, the existence of a vacuum space can be avoided, ensuring better overall smoothness during the filling process, and the internal valve core can move regularly when used in conjunction, and the activity smoothness and safety of use are better during use, thereby effectively improving the accuracy of the exhaust position during exhaust, and the overall durability during use is stronger, which can meet the use requirements of application equipment with relatively high safety and precision requirements. It can achieve the dual functions of exhausting and inhaling air when in use, and can ensure that the interior is fully enclosed when the internal liquid is fully loaded. At the same time, it can also withstand relatively large pressure, making it safer to use and having relatively low cost.
[0023] Preferably, the diameter of the main body delivery fitting hole 7 is larger than the diameter of the exhaust transition hole arranged at the center position of the sealing safety fitting pad 9 and the exhaust safety fitting ring 8, so that the safety during the combined use is more reliable.
[0024] Preferably, the exhaust safety fitting ring 8 is provided with sealing fitting safety grooves on both the upper and lower sides, so that the sealing of the upper and lower positions during the fitting connection can be more reliable, and the overall safety during use can be effectively improved. When sealing, it can achieve a double sealing fitting connection effect, and the fitting safety during use can be further improved.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
